Yes, of course it is.....The networks and the media have the Debate Commission to relieve them of reporting on third party candidates, even ones with viability like Gary Johnson.
The two party duopoly wants a binary choice, period. They system would rather force a choice between two reviled candidates than allow other legitimate choices who have ballot status and significant support.
So again. If you get called by a pollster, tell them Johnson, just to mess with the system.
